Firmware: PreenFM2 Bug report
« on: November 19, 2013, 09:41:41 AM »
Please report here any bug you may find.
Don't forget to specify the firmware you use. It shows up when you switch on the PreenFM2.

Thanks

Hi Martin,

The LCD misspellings must be because of the tight timing i use that works with the LCD provided with Kit.
What LCD do you use ?
I'll upload today a version with larger delay.

For the bank and combo patches, i've just tried and it works.
What Usb drive do you use ?
What error do you get ?
And last question, can you read and save on bank created from the menu ? tools->create->bank  / combo ?
If you haven't try, I would suggest you to download again the zip file, format your USB stick (slow formating) and extract the zip again on it.

Thanks for the information.

For your LCD problem :
Could you try the firmwares that are in this zip file : https://dl.dropboxusercontent.com/u/41654198/preenfm2/firmwares/fix_lcd.zip
In the order 35, 36, 37, 38.
And let me know the first one that fix your problem, if any.
Just extract them in "pfm2" on your USB drive and power the preenFM while pressing the "OP" button. Then select the one to flash. (but you may already know that ;-)

Regarding the banks, what you have is totally normal, "combo" and "bank" are here to allow you to save your presets. They all contains the same preset by default.

Thanks

Thanks for the feedback.

What you describe is normal the bootloader (flash mode) still use the old 34 value.
I'll make some test under heavy load with 38 and if everything works fine, it will be the default value in the next firmware.

The newhaven OLED has all sorts of issues as well.  It only displays something when the menu button is pressed (nothing on start up) and then instead of increment values, it scrolls everything left to right.  Everything is misaligned also and it made all sorts of noise (the display actually made noise) at the 34 setting.  If it's any help, I used the same display with the Preen 1 without issues

Have you tried the other firmware in the zip above.
Could you confirm me that the firmware 38 does fix the problem with your LCD ?
If yes i'll release it as an official patch today.

Which Oled do you have  ?

Thanks,
Xavier

I tried all the alternate firmwares and all had the same behavior. This is the one I use: http://www.mouser.com/ds/2/291/NHD-0420DZW-AY5-30221.pdf

I plugged an OLED screen i had on a PreenFM1 and i confirm it does not  work. (Just realized it's exactly the same as yours).
Having it working is number one on my priority list. I'll work on that tomorrow.
